Vor dem Gleitschalungsfertiger wird von einem Lastwagen aus oder mit Hilfe von speziellen Geräten, wie Beschickungseinrichtungen Frischbeton aufgeschüttet. Mit Hilfe von Verteilerschnecken oder einem Verteilerschwert wird der Beton zunächst quer zur Fahrtrichtung gleichmäßig verteilt. Anschließend quer zur Fahrtrichtung hin- und herbewegt wird, glättet eine Querglätteinrichtung, die leichte Unebenheiten der noch frischen Betondecke. Hinter der Querglätteinrichtung ist eine Längsglätteinrichtung angeordnet, die die Oberfläche der noch frischen Betondecke zusätzlich glättet.Slipform pavers provide a continuous advance concreted areas, such as roads, concrete slopes and the like. In front of the slipform paver is from a truck or with the help of special devices such as loading devices Fresh concrete piled up. With the help of augers or The concrete is first turned crosswise to the direction of travel equally distributed. Subsequently is moved back and forth across the direction of travel, smoothes a cross smoothing device that slight bumps in the still fresh concrete surface. A longitudinal smoothing device is located behind the transverse smoothing device arranged the additional the surface of the still fresh concrete surface smoothes.

Aus der DE-A-30 36 234 ist eine Vorrichtung zum Glätten einer Betonbelagsoberfläche bekannt, die einen Quer- und einen Längsglätter zum Beseitigen der Unebenheiten des Frischbetons verwendet. Der Querglätter besteht aus einer Pendelbohle, die sich unmittelbar hinter einer Einbaubohle befindet. Die Pendelbohle kann in ihrer Höhe durch zwei Handräder verstellt werden. Die Pendelbewegung der Pendelbohle wird mit Hilfe eines Exzenter-Antriebes realisiert. Der Längsglätter besteht aus einem Glättblech, das mittels zweier Strebenpaare gelenkig an einem Laufwagen aufgehängt ist, der an einem Querträger beweglich gelagert, quer zur Fahrtrichtung über die Maschinenbreite verfahrbar ist. Dieser Querträger ist über Auslegearme fest mit dem Maschinenrahmen verbunden und, in Fahrtrichtung gesehen, weit hinter dem Querglätter angeordnet. Über einen Exzenter-Antrieb wird das Glättblech parallel zur Fahrtrichtung hin- und herbewegt. Die Aufhängung des Längsbleches ist dabei so gestaltet, daß die Bewegung des Längsbleches der Oberflächenkontur des Frischbetons angepaßt ist.DE-A-30 36 234 describes a device for smoothing a Concrete surface known, which has a cross and a longitudinal smoother used to remove the unevenness of the fresh concrete. The cross straightener consists of a pendulum plank, which is immediately located behind a screed. The pendulum plank can be adjusted in height using two handwheels. The The pendulum movement of the screed is carried out with the help of an eccentric drive realized. The length straightener consists of a smoothing plate, this is articulated on a carriage by means of two pairs of struts is suspended, movably mounted on a cross member, can be moved across the machine width transversely to the direction of travel.

This is done via an eccentric drive The smoothing plate is moved back and forth parallel to the direction of travel. The Suspension of the longitudinal plate is designed so that the movement of the longitudinal plate of the surface contour of the fresh concrete is adjusted.

Nachteilig ist dabei, daß der Platzbedarf durch die Anordnung des Querglätters und des Längsglätters sehr groß ist. Dadurch, daß der Längsglätter in Fahrtrichtung gesehen, sehr weit nach hinten reicht, muß eine zusätzliche Abstützung für den Längsglätter vorgesehen werden. Ein weiteres Problem besteht darin, daß der bekannte Längsglätter nicht bei einem dachförmigen Profil der Betonbelagoberfläche einsetzbar ist.The disadvantage here is that the space required by the arrangement of the cross smoothing and the longitudinal smoothing is very large. Thereby, that the longitudinal smoother seen in the direction of travel, very far behind enough at the back, an additional support for the longitudinal straightener be provided. Another problem is that the well-known longitudinal smoother not with a roof-shaped profile the concrete surface can be used.

Nach der Erfindung ist demzufolge vorgesehen, daß die Querglätteinrichtung als Führungseinrichtung für eine zusätzliche über die Arbeitsbreite verstellbare Arbeitseinrichtung verwendet wird. Dadurch kann die Baulänge der Maschine erheblich verkürzt werden, wobei ein zusätzlicher Querträger als Führungseinrichtung für die Arbeitseinrichtung entfallen kann. Desweiteren ist gewährleistet, daß die Arbeitseinrichtung der von der Querglätteinrichtung eingestellten Dachform der Betonbelagsoberfläche exakt folgt. Bei Einbau von Verlängerungssegmenten bis zu einer Arbeitsbreite von ca. 16 m wird gleichzeitig auch die Führungseinrichtung für die Arbeitsrichtung verlängert, ohne daß ein weiterer Umbau erforderlich wäre.The invention advantageously provides that the transverse smoothing device for the production of a roof-shaped profile Concrete surface from two, in the middle of the working width there is articulated cross screed, and that a working device is movable on the transverse smoothing device is attached and over the entire working width of the machine frame is movable on the transverse smoothing device.
